What is the one focal point that catches every team member’s attention at the same time every day? Of course it is their Scrum board. Some teams go through the motions and use their Scrum board because they are told to; for effective teams the board is a way to collaborate, manage work in process, keep track of impediments and know whether or not they are going to meet the sprint goal. Effective teams turn their board into a highly-visible collection of critical information about their effort. It becomes the heartbeat of the team and helps set the cadence for each sprint.
Their board might look something like this:
Sprint Dates and Goal – as a reminder of the goal and the timeline. Seeing the sprint dates can be helpful if users who will be testing attend the standups so that they understand the sprint timing.
Columns for each step in their development process – This can be as simple or as complex as the team wants – it usually evolves as the team learns and tweaks its process to ensure a smooth flow of stories. In the example above, the team experienced issues with too many stories waiting for user testing. They created a column to show which stories are ready for user testing to make it clear to users when something is ready for them to test. During standups, the Scrum Master points out any columns where an excessive number of stories are piling up. Even with Scrum, the team may set limits for how many stories may accumulate in each column before team members swarm to address a bottleneck.
Sprint Calendar – during sprint planning the team members estimate on which days of the sprint they think stories will be Done and also when they will likely reach any other significant milestones in the team’s process such as being ready for user testing. This is a way of performing a sanity check for the sprint plan. It is also a way for the team to gauge whether or not it is on track during the sprint. When user testing is part of the Definition of Done, it allows the users to plan when they will be performing this testing. Putting team members’ planned vacation days on this calendar avoids surprises in the middle of the sprint. It can also help to put key SME’s or users’ vacation days on the calendar if these could impact the sprint.
Impediments – unresolved impediments. Making these visible is a way to track them and may have the side benefit of prompting outside stakeholders who attend the standup or visit with the team to help the Scrum Master by finding other ways to resolve them.
Additional Stories – these are stories at the top of the Product Backlog that are ready to be brought into a sprint but that are not part of the current Sprint Backlog. These are posted on the board so that they are readily available in case the team reaches the sprint goal early and can complete some additional stories in this sprint. Note that these are not called “Stretch Goals”. That term can be perceived negatively by the team, almost as if they are not pushing hard enough in the first place to meet the sprint goal.
Release Burnup – the bigger picture of what the team is working towards. This help avoid the sense of being in an endless churn of sprints with no end in sight.
For teams using Kanban, many elements on this board still apply but may need slight modification. Note the use of colors throughout the board. It is amazing how teams will adopt color schemes or symbols that communicate the state of their work, highlight important events, serve as key reminders, etc. One type of information not included on the example above is an area for Technical Debt. Creating an open area on the board for this invites the team members to note it as soon as it becomes apparent to them. These notes can then be translated into backlog items during grooming. This encourages open discussion about technical debt and surfaces this information rather than just having it in the team members’ heads.
A note for teams that use online/electronic Scrum or Kanban boards: additional information such as the PTO calendar, Impediments and release burnup can be captured in story cards and placed in a column dedicated to that background information. The sprint calendar can be captured by putting Due Dates on each electronic story card. On a physical or electronic board, the story cards can contain as much information as the team finds helpful. Typically the story number, title, and number of story points are included.
- The Scrum or Kanban board can be used to communicate much more than just the status of the stories and tasks.
- The information on this board should reflect each team’s personality and process. It will evolve as the team learns.
- The Scrum Master can help the team during the standup by directing their attention to potential trouble spots on the board.
For a Scrum Master introducing agile to a team, there is a balance between implementing concepts and practices at a pace that does not overwhelm the team and demonstrating the benefits as early as possible to build momentum and support within the organization.
Each situation is different, but let’s assume that an organization wants to use Scrum and there is an experienced Scrum Master who has been asked to lead a team of people that are experienced with waterfall approaches and are new to agile. Also assume a reasonable level of management support. How should the Scrum Master go about implementing agile practices on the team? For an experienced agile practitioner, the practices are second nature so it can be tempting to try to introduce it all at once, but the reality is that it must be gradually introduced in bite-sized chunks. The key question is which practices should be introduced first and which practices must be implemented in the longer term? Here are some suggestions:
Before starting the first sprint, there are some things that need to be put in place:
- Secure a Product Owner (PO). In many organizations this might be a product manager or representative from a business unit. This requires a serious time commitment and product insight so it should not be an afterthought.
- Secure a team where the people will be dedicated just to this team, rather than juggling several different projects at once. This can be a big shift for organizations accustomed to managing project assignments via resource utilization/optimization models tied to specific skillsets.
- Educate the team (including the Product Owner) about agile principles and Scrum. Hiring a Scrum trainer to conduct a two or three day course is ideal, but if lead time or budgets do not allow this, prepare an overview that touches on the agile principles as well as the mechanisms and ceremonies of scrum. The Scrum Reference Card and Build Your Own Scrum are good tools to facilitate this.
- Be careful in comparing agile to waterfall. Disparaging waterfall will not endear agile to people who have delivered successfully using waterfall.
- The new PO will require additional training about what the role involves. If they were a product manager accustomed to working with a project manager (PM), they will need to understand the additional responsibilities that get transferred from the PM to the PO. To get them started, help them understand that they will need to work with the team on a daily basis.
- Change the team’s physical workspace to foster improved collaboration. Sometimes it is as simple as taking down a few cubicle walls. Other times, it involves locating people in the same area if they are spread out around the building. Be thoughtful about this. Done wrong, too many people are jammed into a small area and they can’t move around without bumping into each other. This builds frustration and resentment that leads people to resist and question the approach that brought this change. Also, an area with plenty of wall space is best.
- Pick an iteration length. Start short so that the team can get used to the different ceremonies and rapidly learn from its experiences. This also quickly gives the team and the organization a feel for what happens before/during/after an iteration.
- Populate the initial product backlog:
- Conduct a story writing workshop. Utilize a technique such as story mapping to organize the stories. Don’t get hung up on teaching story mapping techniques – just do it by organizing stories that way on the wall. It will actually be very intuitive to people who are accustomed to structured analysis techniques. A big challenge here will be in writing the stories. If a work breakdown structure (WBS) exists as a result of the initial business case or previous project planning that was done before deciding to use agile, it may be possible to use it as a starting point for populating the product backlog. This depends on the extent to which the WBS aligns with product features vs. technical tasks. The more aligned it is with features, the easier it is to translate. This is an opportunity to reinforce that product backlog items are features and not tasks. Also, team members may correlate this to the design phase of a waterfall project. The focus needs to be on “what” the requirements are and not “how” they will be implemented. Stories need to be written in just enough detail for sizing, not with detailed requirements.
- Get the PO to prioritize the backlog by business value. Don’t be surprised if every item is given a priority of ‘1’ the first time around.
- Create a Definition of Done. This provides the basis for sizing stories. This should include user acceptance testing (avoid the use of “done” and “done done” at all costs!). This will be challenging for a team accustomed to a UAT phase after long design and development phases. Doing this reinforces that the team should write stories that represent testable feature increments rather than individual technical layers of the application.
- Conduct a planning poker session where the team sizes an initial set of backlog items using story points. This can be a big change for teams accustomed to having senior team members provide the estimates. During this process, the Scrum Master needs to make sure all voices on the team are heard. Planning poker is ideal way to do this. The Scrum Master solicits input from all team members, especially when there are significant differences in estimates. So that the team does not feel as though it needs to define every last detail of each story, help team understand that this is not the last time these stories will be discussed; detailed requirements will be covered in depth once the sprint starts.
- This next step depends on the project and organization. If the organization views the project as an agile incubator, the team might have the leeway not to commit to an overall release plan for the product until a few sprints have been completed and the velocity is understood. If not, you may need to use an old project planning approach to derive a delivery date to satisfy the organization until a release plan can be formulated. Be very careful about providing enough buffer for unknowns – any dates that are published may become the benchmark against which success or failure of the effort will be measured. If possible, characterize any release dates as preliminary until the team has had a chance to run a few sprints.
The First Sprint
- Plan the sprint.
- Set firm start and end dates for sprint. Go with either a 1 or 2 week sprint. A 3 or 4 week sprint length is not recommended because it is harder to convince PO not to change the contents of a sprint if it is longer. Also, longer sprints involve larger numbers of stories for a larger team, which can be difficult for them to manage. A shorter sprint length allows the team to demonstrate results quickly.
- Calculate the team’s hours of capacity to do work on user stories during the sprint, factoring in sprint length, time for meetings, vacation time, etc.
- Conduct the sprint planning meeting. The first part should involve the development team and the PO. Review the user stories on the backlog starting with the highest priority items. The team should ask the PO any questions they need to help them understand how to task out each story. The PO can stay for second part if they want. Create tasks for each story. Make tasks granular enough (max 6-8 hours) so that it will be easy to have multiple people working on each story. Continue to add stories until team’s hours of capacity for the sprint are used up.
- Ask everyone on the team if they are comfortable committing to delivering these stories in the timeframe of the sprint and if they have any concerns or reservations. Go around the table and ask each person – it can reveal some insights that people might not otherwise volunteer.
- Set up a story/task board in the team area. Even though the team might have software for sprint planning, go with high-visibility, tactile information radiators. This is important because it helps the team learn that it needs to be self-organizing/self-assigning. The team should update the board throughout the sprint, not the Scrum Master. The Scrum Master needs to change culture of having the project plan buried in project planning software like MS Project and only being maintained by the PM. This also starts to build culture of transparency with stakeholders. Invite stakeholders to visit the team’s work area to view status of current iteration. Of course, be careful that they don’t interfere by trying to change priorities or introduce new stories.
- Start the first sprint.
- Do daily standups. Start by helping team understand the purpose and the basics.
- Some people on the team may have heard the agile myth about “no documentation”. This is the time to start establishing culture of lean, maintainable documentation that has value through the lifetime of the product. A new team will only be able to bite off so much new stuff at one time. If they are accustomed to some type of UX or use case document, use that artifact (during the first sprint) as a transition into user acceptance test cases.
- Coach team members that the first thing that they need to do when they pick up a new user story to work on is to get with the PO and applicable users to discuss detailed requirements (since the team didn’t hammer out every last detail of the story during grooming or planning, right?). Reinforce with the PO that they need to be prepared to work with team members on a daily basis.
- While the Scrum Master’s eventual goal is a team that limits WIP and individuals self-assign tasks, don’t necessarily expect that to happen in the first sprint. Remember – people on the team are probably accustomed to having their tasks assigned to them by the PM or tech lead via project plans. Initially, the Scrum Master may need to ask for volunteers for tasks, or as team members report that they are wrapping up a task, the Scrum Master may need to ask them which task they will work on next. Team member will typically look at the next available story that no one is working on. Steer them instead to first look for tasks they can work on for stories that are already underway but not yet complete.
- Start tracking the team’s burn down and post in the team work area.
- Run interference if the PO or other business stakeholders try to change the stories in the sprint. This is another reason to keep sprints short (max 2 weeks) at first. It is easier to argue against changing the contents of a sprint when the next sprint is less than 2 week away.
- Conclude the sprint on the planned end date. DO NOT extend the sprint under any circumstances, even if it will take ‘just one more day’ to finish all of the stories. It is important to establish this early as it speaks to the sprint commitment being firm and the importance of sizing/organizing the work so that it can be completed within the iteration.
- Do the retrospective. Keep the format simple initially. “What went well, what did not go well, ideas for improvement” is an easy format. Do not allow anyone from outside the team to attend. Make sure the PO attends because they are part of the team and this meeting is an important way to build trust between the PO and the developers. Ensure attendees know that the Vegas rule applies. At the conclusion of the retrospective ask attendees if it is okay to share ideas that were generated with outsiders – stakeholders will naturally be curious. Ideas that the team does not want to share are not shared outside the team.
- In preparation for the sprint review, prepare a sprint summary document. Show the team’s burn down, stories committed and status of each story at end of sprint.
- Conduct the sprint review. Encourage as many people from around the organization to attend as possible. This is about
- Demonstrating results
- Team members taking pride in their work by showing it off
- Showing the organization that the team is transparent
The development team members (developers, QA people, etc.) should conduct the demos.
The mechanics of the first sprint described above are relatively straightforward, but the reality is that this is all occurring against the backdrop of organizational change:
- Team members are experiencing dramatic change. Their physical work area has changed. They are being asked to commit to delivering something without detailed specifications. No one is telling them which tasks to work on.
- The relationship between business and IT may be very different when using an agile approach. If the PO comes from a business unit and because of the organization’s culture there exists a lack of trust or poor communication between the business unit and IT, the lack of trust and communication issues will not necessarily disappear overnight.
- The organization’s culture may not value or emphasize teamwork. Part of management and the Scrum Master’s jobs is to build a culture where teamwork is highly valued.
The Second Sprint
In the second sprint, the Scrum Master continues to emphasize agile principles and the mechanisms of Scrum.
- The Scrum Master continues to coach regarding self-assignment of tasks. As the Scrum Master backs away a little bit and the team starts to self-organize, others (such as the PO) may feel that the team needs to be directed and step in to direct the team and tell them what to do. The Scrum Master must also coach them not to direct the team.
- The Scrum Master continues to encourage team members to swarm on stories by default rather than only when necessary. Lessons learned from first sprint (e.g. too many stories in progress at the same time) make the purpose of this apparent. Swarming will not happen overnight, but the Scrum Master needs to keep encouraging it.
- Conduct user story grooming meetings during the sprint. In the meetings, continue the mantra of discussing features at “the right level of detail at the right point in time.” Use these meetings to size out the rest of the backlog and to revisit stories likely to be worked on in the next sprint. The product owner may be unprepared for these meetings because they are already overwhelmed by working with the team on the current sprint’s user stories. Sometimes it helps for the Scrum Master to meet separately with the product owner a day or two before a grooming meeting to survey the backlog and discuss the next set of stories to be groomed.
- Encourage the PO to regularly tend to the backlog – not just before grooming or planning meetings.
- Using the team’s velocity from the first sprint, begin working with the product owner to formulate the release plan. It may not be appropriate to go public with it yet. Velocity cannot necessarily be trusted after just one sprint, but doing a preliminary release plan is valuable to get the PO thinking in terms of using the velocity and backlog to formulate a plan.
- Start tracking the team’s burn up and also post in the team work area. The burn up emphasizes that hours worked do not provide business value, only completed user stories do. A graph that shows a steady burn up of completed story points during the sprint (rather than a ”hockey stick” where most of the stories get closed at/near the end of the sprint) is the goal. Don’t necessarily beat the team over the head with this…at this point just introduce it to them and call attention to each story as it is closed during the sprint.
Over subsequent sprints, the Scrum Master should consider introducing some of the following techniques. Of course each situation is unique so he/she will have to gauge whether or not the team is ready for each new practice.
- For teams that are having trouble swarming and have too many stories in progress at the same time, reinforce the concept of WIP limits. For teams that already have a task/scrum board with steps in the process laid out, the WIP limits can easily be established for each step. The team can decide whether they are firm limits not to be exceeded or soft limits that are triggers for conversations.
- Help the team learn the finer points of writing user stories. A book study (e.g. “User Stories Applied” by Mike Cohn) is a good way to do this. Be sure to include the PO in this.
- Test-Driven Development (TDD). The benefits of this can be difficult for a team to grasp. Once the team (including the Product Owner) understands that it is okay to refactor and that it is simply part of progressive elaboration, the benefits of TDD become much more apparent.
- Acceptance Test Driven Development, manual or automated.
- Introduce additional retrospective techniques to help the team learn about itself and identify areas for growth. The Scrum Master will need to judge what type of retrospective is appropriate depending on how the sprint went.
In addition to learning new practices, the team overall needs to learn to be agile, not just to use agile practices.
- Work with team members’ managers to help them develop a broader, t-shaped skillset that allows them to perform a larger variety of technical and non-technical tasks. For specialists, this can be a big shift.
- Help the team to develop an agile mindset by only learning enough about a feature to size and plan it and then really dig into the details of it once it has been pulled into a sprint. One of the most gratifying moments for a Scrum Master can be when the PO says, “We did not think of that aspect of the feature in when we discussed the story. We will just create a new story and handle it in the next sprint” – without taking the team to task for not delivering it in the current sprint.
- When the Scrum Master has been steering the team towards new practices but the team has resisted using them, the Scrum Master may need to let the team fail for a sprint. The Scrum Master needs to help stakeholders understand that this is part of the learning process, and two-week sprints will minimize most of the damage if the team gets off-track.
- Every situation is different so of course there is no “one size fits all” approach to starting with agile. Organization and team dynamics impact the speed and extent to which agile is adopted.
- As the team becomes more comfortable with the agile approach, the Scrum Master should adapt his/her approach to be in more of a supporting role for the team.
- Occasionally the team will forget lessons learned from a few sprints ago and revert to old habits. The Scrum Master can bring previous retrospective conversations back into focus to help the team avoid making the same mistakes.
Swarming is the essence of agile teamwork. Everyone on the team pitches in to push stories over the finish line. Egos are left at the door and team members sometimes operate outside of their comfort zones so that the team can deliver on its commitments.
Sprint planning sets the table for effective swarming. Tasks for all types of work are represented in the sprint plan. For a software development effort, this includes GUI creation, web development, database development, QA, and any other work needed for the sprint. A user story task list with the team’s estimates might look like:
In sprint planning, the team estimates stories and tasks until they fill up their capacity (available hours to work on tasks) for the period of time covered by the sprint. This is different from velocity, which is based on user story points or ideal days and provides a rough measure of what can be in a sprint as a high-level release planning tool.
During sprint execution, the team determines based on its WIP limits or other factors whether to swarm on a story. For example, Web developers could help out with the Develop QA test scripts task if needed to get a story done as the end of the sprint approaches.
Teams who are having trouble swarming may be the victims of their own sprint plan. Some toolsets or teams treat certain types of work differently in the sprint plan. For example, Microsoft’s Team Foundation Server (TFS) uses the concept of Test Points as a way of estimating the QA testing tasks and provides progress reporting based on burning up these points. The plan for this story then looks like:
Notice that the QA tasks are no longer in the task list as the developers’ tasks. As a result, the developers create a sprint plan using the development tasks. They add stories and tasks to the plan until they have filled all of the projected development hours capacity for the sprint. The QA people create a sprint plan based on test points. While developers and QA are working on the same user stories, they have lost their common pool of work to be completed to get the stories to “done”.
Effective swarming is based on the premise that all team members are responsible all of the work to complete the stories. Creating a second sprint plan for other work on the same sprint creates a barrier that inhibits people from working outside of their pool of tasks.
Common arguments for this approach are:
“QA should not have to provide separate task estimates because test cases completed are a truer measure of progress rather than hours spent on testing.”
This argument might hold water in the purest sense, but does anyone really want to sacrifice team cohesiveness for the sake of generating status reports that are slightly more accurate?
“QA work cannot be accurately estimated because the level of effort depends on how many bugs are in the code.”
The reality is that all work has a certain level of uncertainty and team members use their collective experience to factor that into their time estimates.
If someone insists that QA work is planned separately from the developers’ tasks, I pity the fool who approaches the ScrumMaster mid-sprint and says, “There is more QA work than the QA person can handle. Can we just tell the developers to swarm on the QA work?”During sprint planning, if the developers filled their available sprint capacity with coding tasks, they don’t have capacity to help with testing!
- Maintaining separate plans for different types of work on a story is a barrier to swarming.
- A sprint plan that includes tasks for ALL of the types of work for the stories provides better visibility and whole-team ownership of all tasks.
- All of the tasks should be estimated in hours and counted against the team’s overall capacity.
